From Space.com:
One does not simply walk out of NASA with a moon rock, of course.Sara Arsenault, an employee of the Montreal Science Centre, told Space.com she was so nervous while carrying her precious cargo in April that she missed her first flight back from NASA’s Johnson Space Center in Houston, forcing her to try again.
I had a chance to work with a NASA lunar soil sample kit one time; six different samples encased in plastic. The security involved in getting those samples for a seminar was incredible.
